Product Identity

The Value Brand 1 inch MNPT by 3 inch TBE galvanized steel pipe nipple is a Schedule 40 fitting built for air, gases and potable water systems. Its electric resistance welded construction and corrosion-resistant coating suit commercial and residential plumbing installations.

Installation Checklist

Verify that the mating threads are 1 inch male NPT and that the system operates within 300 psi at 150 degrees Fahrenheit or 150 psi steam at 350 degrees Fahrenheit. Confirm the 1 5/16 inch outside diameter and 3 inch overall length match the available space and Schedule 40 piping layout.

Upgrade Context

This nipple replaces worn or corroded Schedule 40 steel nipples of the same nominal size and thread type. The jump is worth it when the existing fitting shows leaks, thread damage or coating failure that compromises corrosion resistance.

Questions about this item

Does the 1" MNPT x 3" galvanized nipple come with any gaskets or sealant?

The nipple is supplied as a single piece of Schedule 40 galvanized steel pipe with male NPT threads on both ends; gaskets, tape or thread sealant must be purchased separately.

When should I choose this 1" Schedule 40 nipple instead of a different size or schedule?

Choose this 1" nominal size, 3" overall length nipple when the system calls for Schedule 40 wall thickness and a 300 psi pressure rating at 150 °F for air, gases or potable water.

What does the 300 psi @ 150 °F rating mean once the nipple is installed in a real piping system?

It means the welded steel nipple can safely handle up to 300 psi working pressure at temperatures up to 150 °F, and up to 150 psi for steam at 350 °F, provided the rest of the Schedule 40 system is rated accordingly.
